> Git isn't the best but network effects matter.

I think this assertion is too vague and arguably wrong. It's unclear which traits would lead a Git alternative to be claimed as better, and even if those traits, if they exist, are relevant. It's also unclear if the tradeoffs of switching tooling away from Git are worth whatever hypothetical benefit there is to be had.

I would make the bold claim that Git is undoubtedly better than any conceivable alternative, and state that the network effect is a consequence and not a side-effect. Anyone is free to try to argue against it by pointing out concrete arguments.

Git is only better in the same sense that Windows is better than Linux. I really need the tools I use that only run on Windows. I prefer Linux for a lot of things, including daily web development, but the experience of developing Unreal Engine on Linux is lacking. I love fossil and the many features it provides in itself and would use it for everything, except that it doesn't have (working) Intellij plugin for integration, a good GitHub alternative, etc.
